1/93. Unerupted second primary mandibular molar positioned inferior to the second premolar: case report.This report is a clinical case of a 7-year-old child who presented right impacted second primary mandibular molar. This tooth was positioned inferior to the second premolar successor and a supernumerary tooth superior to the second premolar. Clinical examination did not reveal systemic diseases ot trauma in the facial region. Treatment consisted of the extraction of the impacted second primary molar and the supernumerary tooth. Periodic examination was indicated for follow-up.- - - - - - - - - - ranking = 1keywords = molar (Clic here for more details about this article) |
2/93. Primary failure of tooth eruption: a unique case.Primary failure of tooth eruption rarely occurs. This case represents a rare clinical situation and appears to reflect a generalized disturbance in the eruptive process, inasmuch as (1) deciduous and permanent dentition are affected, (2) incisors, molars, and premolars are involved in all quadrants, (3) skeletal and craniofacial growth are within normal limits, and (4) no systemic/genetic anomalies were detected. This is the first such case reported in the literature; diagnosis and management are discussed.- - - - - - - - - - ranking = 0.16666666666667keywords = molar (Clic here for more details about this article) |
3/93. Apparent hypodontia: a case of misdiagnosis.The case of a 12-year-old girl is reported, whose pretreatment radiograph demonstrated agenesis of two premolars and a canine and slow development of the contralateral premolars. A follow-up radiograph taken 1 year later showed initial mineralization of a tooth germ in the site of one of the apparently missing premolars. The cause, diagnosis, and treatment planning implications of delayed mineralization and slow development of second premolars are discussed with reference to the literature.- - - - - - - - - - ranking = 0.33333333333333keywords = molar (Clic here for more details about this article) |
4/93. cleidocranial dysplasia: modern concepts of treatment and a report of an orthodontic resistant case requiring a restorative solution.A case is presented of a young boy with cleidocranial dysplasia, whose multiple supernumerary teeth prevented the eruption of most of his permanent teeth. His maxillary incisor teeth failed to erupt following removal of anterior supernumerary elements and orthodontic traction. Lack of abutment teeth and a difficult maxillary base made prosthetic treatment almost impossible. A horseshoe acrylic denture retained by milled crowns bonded to the deciduous canines and a maxillary first molar proved a very successful restoration. The problems of treating this group of patients are discussed.- - - - - - - - - - ranking = 0.083333333333333keywords = molar (Clic here for more details about this article) |
5/93. Radiographic localization of unerupted teeth: further findings about the vertical tube shift method and other localization techniques.The parallax method (image/tube shift method, Clark's rule, Richards' buccal object rule) is recommended to localize unerupted teeth. Richards' contribution to the development of the parallax method is discussed. The favored method for localization uses a rotational panoramic radiograph in combination with an occlusal radiograph involving a vertical shift of the x-ray tube. The use of this combination when localizing teeth and supernumeraries in the premolar region is illustrated. When taking an occlusal radiograph to localize an unerupted maxillary canine, clinical situations are presented where modification of the vertical angulation of the tube of 70 degrees to 75 degrees or of the horizontal position of the tube is warranted. The limitations of axial (true, cross-sectional, vertex) occlusal radiographs are also explored.- - - - - - - - - - ranking = 0.083333333333333keywords = molar (Clic here for more details about this article) |
6/93. A late developing mandibular premolar supernumerary tooth.This paper presents a case of a patient who developed a mandibular premolar supernumerary tooth between the age of 11 and 20 years. Evidence for the late development of the supernumerary tooth comes from consecutive panoramic radiographs. A review of the international literature concerning late developing supernumerary teeth is included.- - - - - - - - - - ranking = 0.41666666666667keywords = molar (Clic here for more details about this article) |
7/93. Primary failure of eruption in the permanent dentition of siblings.Primary failure of eruption is a condition where there is eruption failure in the permanent dentition with no obvious mechanical cause. It has previously been reported in the literature as a cause of posterior openbite, with a varying degree of familial inheritance. This case report describes two sisters that experienced eruption failure in the permanent dentition, most notably of the first and second molars, with greater severity in the younger sister. Teeth were exposed in both patients and orthodontic traction was applied with little or no success. The report provides further evidence of the genetic contribution to the aetiology of this condition and also highlights the problems in attempting treatment, including exposing to the oral environment teeth that are infra-occluded and difficult to clean effectively.- - - - - - - - - - ranking = 0.083333333333333keywords = molar (Clic here for more details about this article) |

9/93. Histological and analytical studies of a tooth in a patient with cleidocranial dysostosis.A histopathological and analytical study of a permanent tooth from a patient with cleidocranial dysostosis (CCD) was performed. The patient was a 47-year-old woman, who had 10 erupted permanent teeth and 2 partially erupted and 19 completely impacted teeth, including supernumerary teeth. The erupted right upper premolar was extracted and observed using a light microscope and an electron probe X-ray microanalyzer (EPMA). Findings showed enamel hypoplasia, predominantly irregular globular dentin and Tomes' granular layer, and a complete lack of cellular cementum in the ground section. The incremental von Ebner and counter Owen lines were obscure. Comparative quantitative analysis using the EPMA showed that the quantities of calcium and phosphate were lower in the enamel and dentin than those of the control sample.- - - - - - - - - - ranking = 0.083333333333333keywords = molar (Clic here for more details about this article) |
10/93. Submerging deciduous molars--an extraction in time!A case is presented of a 25-year-old man with a submerged lower second deciduous molar and an impacted lower second premolar. Treatment was complicated by the relationship of the teeth to the inferior dental nerve, which necessitated extensive bone removal and mental nerve transposition to remove the submerged and impacted teeth. Early recognition and treatment of the submerging tooth might have prevented the need for such extensive surgery and morbidity at a later date.- - - - - - - - - - ranking = 0.5keywords = molar (Clic here for more details about this article) |
